Last week came the announcement that DC comics character Amanda Waller would be added into the mix in the second season of Arrow and now TV Guide is reporting that “Spartacus” actor Cynthia Addai-Robinson has been cast in the role.

Like the source material, Waller will work for ARGUS in the series and will appear in the sixth episode of the upcoming second season. Waller also runs the Suicide Squad in the comic books, a government sanctioned group composed of villains, which will be introduced in the second season of the series as well when Deadshot (returning guest star Michael Rowe) teams up with Michael Jae White as Bronze Tiger.

In addition to Waller and Bronze Tiger, the second season will feature even more comic book characters and will include Caity Lotz as Black Canary, Kevin Alejandro as Sebastian Blood, Bex Taylor-Klaus as Sin, and the series debut of Barry Allen aka The Flash later in the season.
